As @Shebbe adviced, these LMT are probably the best option. Other DRTs as real LMTs in ACES 1.3
They are really close to Alexa LUTs (the main difference is in the darkest shadows) and they are HDR delivery compatible. Just make sure you install and use it correctly.
And about your screenshots. I guess you’re using ACEScc(t) color science in Resolve project settings. You should turn off OOTF and turn on Use white point adaptation in both Color Space Transform OFX. Otherwise you get incorrect decoding of OETF and wrong whitepoint in the node with your LUT.
But for your task you should use ACES Transform OFX instead. It will un-tonemap highlights roll off of your LUT and undo all the other things, that will be added by ODT in the end. This will give you almost identical result with your LUT (except for fully saturated yellow - it’s the current limitation of inverse ODT).
