Video is actually a rather more interesting subject than audio.
As consumers we do NOT have access to uncompressed video.
ALL video we have access to, including the video on Blu-Ray discs and 4k UHD discs, is significantly compressed.
And, if you do have the opportunity to compare actual uncompressed video to a Blu-Ray or 4k disc, you will see that there ARE visible differences.
Use your computer to generate a few seconds of true uncompressed video - especially containing sharp lines and fine print.
Take a bunch of perfectly sharp still frames and combine them into a video.
Compress it using any of the standard video compression profiles, and you will see that there are in fact significant visible differences, all of which relate to loss of detail or motion or color space compression.
You may find that the losses aren't especially noticeable, and you may be able to trade objectionable artifacts for less objectionable ones, resulting in an "overall improvement".... but there will always be fidelity losses.
Video encoders are notorious for omitting random noise like film grain that was present in the original.
(They do this because true random noise is difficult to encode, and so uses up bandwidth that "could better be used for more important details".)
However, some producers, and some fans, complain that the "film look" of the video is destroyed when the film grain is removed.
(And, if your new digital audio recording omitted the tape noise that was present on the original master tape, would you describe it as an accurate reproduction or not?)
(Incidentally, Darbee is not noise reduction..... it is a sort of dynamic color and detail enhancement process. And, no, I'm not fond of the look it delivers.)

A Lexus has better features. If you are buying a more expensive piece of equipment because it has additional features that you like, that is a good reason to spend more. I have an Oppo BDP103D player, and it has the exact same video and sound quality as my $100 Sony blu-ray player, but it plays DVD-A, SACD, MKV on thumb drives and it has Darbee video noise reduction. It has a whole slew of features that justify the price. When I bought it, they also made a BDP105D, which was the exact same player, except the specs were even further into audio overkill. I passed on that one. No point to throwing good money at sound I can't hear.
You might want to look into Handbrake. If you plan to save that video you downloaded, you can compress it to MP4 format with no real quality loss. You just need to use the proper compression scheme. In fact, if you really understand the settings in Handbrake, you can end up with a MP4 version that is *better* than the uncompressed blu-ray rip.
Too bad the testing procedures weren't!
