Which DAC are you using?
Your debug info shows (under MQA capability header) that you aren’t using an MQA enabled DAC or at least have it set that you don’t have an MQA capable DAC and looks like it is not set to autodetect if you do… best you are going to get in that case is one software unfold to 88.2 or 96kHz depending on the base rate; to unfold it to 176.4/192kHz or higher you need MQA hardware to do the second or subsequent unfolding. MQA hardware also has a specific filter for MQA encoded content. I have read that there could be a partial benefit to doing the single software unfold; though personally, I generally just use the HiFi/CD quality setting with non-MQA equipment and leave MQA to capable hardware since it is less fuss and uncertainty.
It’s kind of like watching a 4k HDR BluRay on a non HDR capable 4k TV, you won’t ever truly be able to judge it since it isn’t capable of displaying what the disc and player are able to output. Slightly different scenario, but similar enough to understand the situation.
Also, upsampling would destroy the MQA encoding as far as I know, as you said there is no use in doing so.
