@jk82 is right, LG does some crazy things, e.g. there's no proper chroma 4:4:4 in PC mode at 4k resolution (and this is just 1 example). It seems it's more important for them to work on ABL algos than picture quality

Yes, but that's what I am using

Nep_XP stated that currently it does more harm than good, since it was implemented back then when DTM wasn't in madvr yet, hence he disabled it.

Which ones? (But I don't think so, see below.)

But that's the same for measurement files as well. Only 1 guy had 200 nits screen, Neo-XP's 150 nits, Manni's 135 nits, all the others are way less (even 50 nits)!
What nits setting did you use when created your measurement files?

Not to mention that's exactly what we want to do as well - the only diff is the way higher nits setting -, the problem is we can't disable the TV's tonemapping.

But if you insist, you can quickly create measurement files for the uploaded clips as well. But in that case post a screenshot of your settings, please.

Well, I don't think it's worth it, there's only minimal difference between passthrough and pixelshader (see below).
