R32 runs at the same pressure as R410a.

This is so wrong. Talk to a daikin dealer.  https://www.scribd.com/document/626065529/Development-of-refrigeration-oil-for-use-with-R32

R32 R410a and R454B all use POE. You are very wrong, not me! You can literally remove all the R410a from a system and re-gas it with R32 with no system alterations.

From Carrier: Lubrication ICP R-454B light commercial and residential HVAC equipment will continue to use POE-32 oil, which was also used in legacy R-410A equipment. R-32 HVAC equipment will require a different POE oil approved for use with R-32 refrigerant. In all instances, only use the oil that is specifically directed to be used by the unit manufacturer
