Dolby Vision for Minix U22X-J (Max) and Ugoos AM6+

Hello, I ve bought an Ugoos am6b+ after I ve learned about coreelec. Its running on a usb stick and I am using it with a Philips 806/12 and samsung q800a + swa 9500s for audio.

I seem to have problems with playback of profile 7 MEL movies. I play them with PlexMod4KODI. I haven’t watched a full movie yet, but I’ve checked out first 5-10 minutes of multiple movies. While FEL movies and profile 8/5 seem to work fine, but MEL movies (Dune 2021 and Gran Turismo tested) seem to cause the player to freak out at certain moments in movies (image freezes while audio is going, than player gui appears, audio lags for a moment and movie skips a second or something like that).

I tried different remuxes and tried packing my own mkv from bdmv files, but the problem still remains on these movies. Turning off DV in settings allows the movies to play them normally in hdr10. At the moment solution seems to be just using Profile 8 remuxes asfaik profile 8 ~ profile 7 MEL (correct me if I am wrong, cause I am a bit of a noob), but having working 7 would be nice.
