Brilliant usage of CSP LUTs.
Unfortunately there is a fundamental thing in your color pipeline that doesn’t really make it an ACES worfklow at all. but you may be able to tune it in to fit.
When you render files out in an ACES colorimetry, you need to stick with ACES2065-1 (AP0). Files can’t be rendered out in ACEScc/cct/cg. Also, they should be saved in uncompressed OpenEXR files (which Photoshop digests very well btw).
Therefore your workflow might go from rendering out ACES2065-1 EXRs out of NUKE and importing them in Photoshop (which handles ACES2065-1 colorspace gracefully)
As additional suggestion: when setting an ACES pipeline in NUKE, you might find beneficial to have ACEScg as working space (but always save ACES plates in ACES2065-1). Then, Photoshop’s “Edit > Color Settings…” and “Edit > Assign Profile…” parameters allow for specifying an output profile in any output-device colorspace you want.
If this doesn’t work, using a CSP LUT like you did is okay, but the LUT should go from ACES2065-1 to the output device of your choice.
That said, Photoshop is still not a “logoed” product; indeed there may still be some subtelties in using it for an ACES workflow (like color-picking and using color palettes).
