The Fengmi is being marketed as a XM upgrade, so I would expect similar performance from both. I only had little time to play with it before giving it away to a local community centre. Billy Lynn did look OK, but Paddington 2 had the same marmalade issue.
Black level is adequate at best, as I suspect the low power pico chipset is used in both the FM and Lune. I don't have access to a reference monitor, so have no idea how a real 4000nits image or BT2020 should look like. But to these untrained eyes BT709 colour gamut coverage seems pretty decent, although I did not get a chance to test if SDR/BT2020 could be displayed properly.
The main issue with these cheap single laser dlp is achieving acceptable colour balance in HDR and SDR, and access to the low level adjustments in factory setting may be required. This is exposed in the Lune, but the FM has to be rooted first. FM also did not specify if the RGB colour wheel is used. That may complicate the calibration process.
Have fun with the FM.
