Assumption that hybrids are essentially EVs glosses over all the fine details that make a good EV. All ICE engines are "essentially identical" too, but there's a world of difference between ICE manufacturers. VW Beetle has an engine in the rear, but it doesn't make it a Lambo.
Plug-in hybrids all use AC charging or at best equally slow DC charging. OTOH BEVs compete on maximizing the charging curve, which is something that has never been a consideration in PHEVs. This requires dealing with much higher voltages and stress on the battery.
Hybrids don't need active temperature management for their batteries, because they never push the batteries that hard, and there's always an ICE engine to generate heat if needed. OTOH thermal management and battery conditioning, and efficient A/C is an important complex piece of BEVs.
Hybrids don't need to maximize their efficiency, since their electric range isn't as important, and even a just-okay electric motor is going to improve efficiency of an ICE engine. OTOH in BEVs every last bit of efficiency matters, since that's a factor in range, weight, and cost. Toyota's bz4x efficiency looks poor compared to BEVs from VW and Hyundai, and they're all noticeably worse than Tesla's.
Batteries in hybrids are relatively small, so they can get away with worse energy density. You can't put 10 PHEV batteries together to make a good BEV.
And legacy automakers still treat software as a nuisance to outsource, instead of a critical component of an EV. I don't mean self-driving publicity stunts, but basics like route planning that includes appropriate charging stops. Software from legacy automakers treats chargers like gas stations, often without real-time speed and availability data. They will send you to some random hotel charger that takes 11 hours to charge, is customer-only and already taken, instead of a rapid 20-minute charger that is just a bit further away.
