Most people wouldnt know unless 1) they are already used to dolby vision, 2) they have 2 different TV at the same time (one w dv vs one without) that they can tell the difference side by side. I'm not saying DV is bad, the fact is its the standard now when it comes to HDR, but most consumers would struggle to point out the difference
As long the image looks good to your eyes is all that matters. To hell with image accuracy, yeah I'm gonna get flamed for this but in the end you buy your TV to enjoy according to what your eyes perceive. First week I have my TV, i set it up accordingly to have the most accurate settings, ok not bad I thought, image look good. Then onwards I started playing around with settings that are deemed illegal by enthuasiast (eg: Contrast Enhancer etc), and to me the image looked even better. Yes its probably not accurate at this point but damm I just like how it looks and everyone will be wowed by it as well
Actually Dolby Vision came out a year before HDR10 on 2014. It is actually not just a standard but an "absolute standard" for HDR format. It's already capable of mastering up to peak brightness of 10,000 nits and 12 bit depth representing 68.7 billion colors (of course there are no commercially available display that can support 12 bit yet) vs 10 bit 1.07 billion on the HDR10, dynamic vs static metadata.
Basically, what Dolby created is a mastering workflow for content creators so contents displayed can be as consistent as possible across so many TV brands that come with Dolby Vision with Samsung being an exception.

So it's up to the TV to display the contents based on different tone map, brightness clipping, roll-off and etc capabilities. You can read up more why there is a need for absolute standard when contents slowly shift from SDR (normally display with 100 nits capabilities CRT last time) to HDR.
Not saying using contrast enhancer or saturated color is wrong, you can adjust whatever that fits your viewing experience for the wow factor. But for me, I can definitely tell DV vs HDR10 even on the same set of TV, even more so on OLED TVs and personally feel much more satisfied knowing I am viewing a well mastered content. Haha.
