I was at their TV conference.  I must say the Q9fn blow me away  , despite owning an OLED .  The colors just look so damn good .
Just from my bare eyes alone , I couldn't actually tell if it is an OLED or LED, it was very very bright as well , never seen a TV so bright before especially around the edge

My only problem with it , is the black crushing was a little strong , probably due to the Ultra Aggressive FALD , when they switched over to those small sparkling light dots , they become quite dim at times .

got la. I just picked mine up last Friday from Sen Heng in SS2. Pleasantly surprised to know that they price matched with the pricing on Lazada..

Paid on Friday, they delivered Saturday noon 

Nope , I don't think Sony plans to update supports of DV for x7000e  , only for their High End Pricey LED and OLEDS .
New Unit ?

RM 4850 for a 65 inches premium TV with Wide Color Gamut is quite a nice offer .

Although You may also want to look into NU8000 , which is this year's model . It is quite a lot brighter than MU8000

I don't think its local dimming will work too well , because its an Edge lit LED TV . 
Only Sony is known to have made excellent edge lit Local dimming TV as of today.

If midrange TV hdr performance poor. Uhd movie will become too dim or not ?

That is mean 2018 year 65inch TV in malaysia market only samsung q9fn & oled can play well uhd hdr movie. Very limited choice.

Nope. There is no Dolby Vision support via HDMI or streaming for any Sony tv except for Z9D, X9500E, X9400E, X9300E, A1 (and some 2018 models which are not mentioned here).
Only Sony TVs with the X1 Extreme chipset get DV.

DV support is like HDR support, it doesn't mean anything if its on a low end tv because it may only make the PQ worse rather than better. If at all it manages to make the PQ better, its a fluke that happens for a particular tv show or movie. Even on high end TVs it only makes a subtle difference (if any at all) in most cases. So, DV for now should not be a main consideration to buy a tv especially if you are playing at the budget end of the scale.

Resolution (4k/8k) doesn't make that much of a difference, so your purchasing logic is not very sound. I would not pay a single cent more for an 8k tv right now (if there was one to buy in the first place - no that Sharp tv that you are thinking about right now is not really 8K) since it will make all non 8k/4k sources upscale very badly. In fact I will not buy an 8K tv until 4k is the most common resolution for broadcast tv which will probably happen sometime in 2030.

Prices will eventually come down so you can wait and see until prices become reasonable for you. In the meantime, just buy the Hisense 5010 and enjoy 

Oppo firmware for Sony's low latency DV is coming soon.
Got LG Oled 65" for RM4k? gogo2's requirements not fulfilled lah 

Thanks for reply.  In your post,  contrast is important factor for Hdr performance.  I should avoid Sony XF85 which is IPS panel (except 85 inch) .  Samsung 2018 qled Tv is good choice , but because they put new feature Auto low latency mode for xbox one x . This new nice feature make all exiting any brand Av receiver not compatible with  Samsung 2018 premium TV which start from NU8000 to Q9FN .  Many 10bit 4k Hdr device cannot pass through video from av receiver to TV .  But the device direct plug in TV is function normally.  So I still need to observe Samsung team can solve this problem with Firmware or not. IF not, I have to wait another year, hope Sony bring some 65 inch premium LED TV next year. Or take the burn in risk to buy LG OLED C8.

I am not rich guy. I just upgrade to new  Hdmi 2.0 AV amp  for dolby atmos & DTS X this year. No way, I will buy a new av receiver because Samsung TV hdmi handshake problem. 

LG OLEDs from 2018 does come with a new logo dimming features in additional to Picture Shifting and Pixel Refresher  .

It turns down the brightness of static logos by roughly 20%. This will probably slightly reduce the chance of getting BI , still the 20% is nothing much since these 2018 panels are quite damn bright.
LG and some retailers also provide warranty for "burn marks" ( according to them ) for the first few years , so you shouldn't need to worry too much about burn in issues , at least not for the first few years within the warranty period.

With that being said , if your family watch channels with static logos , that can problematic in the long term .

I won't say it is competely safe , everything come with a risk . It is whether if the Picture Quality offered by OLED worth trading the risk of getting BI  . For me and many of the OLED owners around here  , it is worth every penny I have spent on it , so much that I am a proud owner of 3 OLEDs right now
The important thing here is to understand why is the screen is vulnerable to BI , because of the uneven aging of the OLED pixels .
Static logos tend to be bright , colorful . The brightest candle also burn out the fastest , the same logic applies here.

So the key to avoid Burn Ins ,  is to vary the purpose you used TV for . Playing games for awhile , watching sport channels of 2 hours , use it as display gallery for 30 minutes , back to watching HDR shows on Netflix etc etc
There also a massive flaw on these OLED TVs .  Once you get used to owning one , you will not want to go to cinema , because you will keep staring at the black portion of the Cinema screen and wondering , why does her hair looks like gray
