What differences have your found in terms of picture quality ? It should be equal or better than Hisense U7H which is a very color accurate screen. Hisense do not offer any artificial enhancement such as LG's cinema mode. You will get to see how the movie is graded with no fake over the top grading.
There are cinema modes in Hisense but they don't offer over the top grading and are very neutral looking. Have you tried cinema day and cinema night ? Both are quite color accurate.
The colors are a bit saturated, and reds and greens are quite prominent, but that is not the major issue, it can be adjusted to your liking, the issue is with the panel quality, it's a QLED so it should have deep blacks as my Mi QLED does, but somehow the blacks on this Hisense looks like a very dark shade of blue, It also has a lot of noise in those blacks, I cannot seem to capture it on camera, but its quite noticeable in person. I am watching it from about 8 Feet away and I can still notice it so I don't really know what to do.
The audio quality sucks, like it really really sucks, Imagine a TV with bad speakers like most sub 20K range TVs and then just add an equally bad subwoofer to it. the audio is not at all crisp, you cannot differentiate the tones of the music playing, it just has a bit of bass, My Mi's QLED speakers on the other hand are 10X better than the speakers on this E7K PRO, it sounds a lot better and has bass too even without a subwoofer.
Then there is the software, lets say if this was a 20-30K TV I would have been fine, but for a 50K TV this software just doesn't cut it, Vidaa OS should pretty much be in a development phase, It lacks a lot of basic features, it lacks apps, You cannot even uninstall default apps that came with your TV. so I am stuck with apps that I don't need or never ever going to use for the remainder of its life.
