We should not leave this here, even though you have found a solution that works for you.
If the picture quality you get when playing UHD discs is significantly better when using Source Direct than when using the equivalent Custom video output settings -- i.e., the settings that send the same signal to your Display -- then something is WRONG.
Source Direct bypasses certain video processing in the player, in addition to sending out the video resolution of the content unscaled. But you are sending 4K/24 4:2:2 12b either way so the resolution part of this is not in play.
HOWEVER, if you have any of the Picture Adjustment settings in the OPPO changed from their Factory Default (0) values, switching to Source Direct bypasses those settings.
So the first thing to do is to go into Setup > Video Output Setup > Picture Adjustment and confirm that every one of the setting lines in there are set to 0.
Next, if you are in the habit of using the Zoom feature in the OPPO, Source Direct also bypasses that.
Now, if you find all the Picture Adjustment settings are indeed set to 0, and you do NOT use the Zoom function, this difference between Source Direct and the equivalent output via the Custom video settings is NOT NORMAL.
I.e., your player may need hardware service. For example, the settings memory may be broken so that the player IS applying Picture Adjustments (when you are not using Source Direct).
Again, presuming you aren't actually using either Zoom or the Picture Adjustments, Source Direct should look the same as the equivalent Custom video choices.
If you can quantify the type of difference you are seeing with Custom vs. Source Direct, that might lead to an answer. But I would not let this slide, because if there's a hardware fault in your player it is best to get that nailed down.
