No I think it will not work as expected for movable 3D LUT, since
movable 3D LUT is a MPC capability.
I have actually sent a patch in the past to clarify this on DCN401. So,
this check doesn't cover this driver anymore, for example.

But I also don't know how to make a more generic check in this movable
3D LUT case.
Any better idea?

In addition to "caps.color.dpp.hw_3d_lut", "caps.color.mpc.num_3dluts"
in theory may be used together.
This is specific to AMD and has no impacts on the API, and I'd suggest
to keep what it is now as this is already verified on a hardware
(DCN3.2) and get this patchset merged. I will verify new solution on
more AMD hardware.
