NOTE : MY apologies for going off-topic , as this involves discussion of more than Hisense TVs.
You are touching several subjects here at once .
The screen coating has no direct impact on the native contrast ratio of TVs .
Most of the current TV displays on market use a form of glossy screen , it is a matter of semi gloss , normal gloss or full gloss .
Full gloss screens are more pricey than the semi glossy because it is able to reflect more lights off the screen . Therefore under the influence of strong glare, it can retain the black levels better on the surface of the display . This alone has nothing to do with the TV's native ability to display black levels , which we will discuss below.
With interference of ambient lights , it is rather hard for untrained eyes to distinguish true black levels . But the TV with better screen coating will generally look better in a brighter room. Most , if not all of Hisense TVs share the same semi gloss screen finish , while all of the current OLEDs use the higher end full gloss coating , they are not in the same league .
Next , we will talk about the VA TV's contrast ratio.
VA TVs are known to have great native contrast rating, it can show incredibly deep "blackness" which has dramatic impact on picture quality .
However VA TV is still LED-LCD based screen , no matter how hard they try , they cannot compete with OLED pixel levels of light controls . Maybe one day when they are able to squeeze 10000 localized dimming zones in a consumer TV , that is when we can expect an " almost OLED " performance .
To better understand the difference, here is a comparison between a VA TV of 6000:1 contrast ratio (which is pretty good ) and an OLED .
The following picture is taken from a scene in Guardians of the Galaxy 2 , both TVs are using their most accurate picture settings , I trust you can instantly tell which is which.

You are mixing 2 different things together, the screen coating quality and the native contrast ratio , and comparing them with something that is completely different.
If you want to make a compliment on a TV , it is fine to just say the TV has great PQ . Almost OLED is a very bold claim , regardless of whichever TV quality you are talking about back there .
Thanks for the informative post! I get your point about screen coating and contrast ratio / light control of OLEDs.
Maybe it's just our different definition of "almost OLED like" black levels which I was referring to. I was just simply referring to my untrained eye's perceived deepness of the blacks on the LED Panasonic screen against adjacent OLED panasonic in the showroom:). I don't claim the LEDs to have the same contrast ratio as OLEDs though, simply due to the self emissive nature of OLEDs. A division by true zero always wins technically.
As for the screenshots of the VA vs OLED, yeah the difference is quite pronounced. However, looks as though tone mapping might have also played some role as the blacks are really crushed in the OLED.
Anyway, back to the Hisense m5010 model which aviecena2020 was asking about (or any other TV):
If you ask an expert if the m5010 is good or not, he/she might say it's terrible.
If you ask a layman like me if the m5010 is good or not, then I'd say it looks pretty good. Good price for the sort of picture quality you get.
lol
My personal opinion: Best you go to the showroom and take a look. Play varying normal/HDR video clips and watch.
As long as you feel like the picture is good enough FOR YOU and not in the crappy category, then I'd say go for it if you'd like to keep cost low. You do get what you pay for, but sometimes what you get is good enough.
I think many (most?) people don't really perceive the improved picture quality of higher end TV vs average TVs in their daily use (i.e. watch Astro, movies, etc) unless you get into OLED category. One you get engrossed in the show/movie, you don't really perceive them all too much as long as it's not crappy.
What most people will perceive though, is screen size and motion. Screen size gives you the immersiveness. Bad motion gets distracting.
Personally for me, I'd pay a bit more and go for the more popular brands simply because of their experience, support & warranty. Haha.
