No, they're really not high end (at least not in developed countries). Any upper-middle class person can afford the best smartphone on the market. There is no meaningful exclusivity. It's not like with luxury cars where there are real high end products available that are completely out of reach.
I think electronics stand out as an area where veblen goods don’t really exist. Partially this is due to scale vs bespoke artisanal works.
That is the differentiation between a 50k vs 200k vs 1M car is often the hand crafted mechanical and luxury touches. Often the core platform of these vehicles is even shared in the case of the VW group and its various halo brands. The things that make a luxury car better are not mass produced.
One cannot hand craft an artisanal CPU better than Apple/Arm designs in a TSMC fab, nor a screen better than Sharp/Samsung, nor a cellular modem better than Apple/Qualcomm, etc. The things that make electronics better are the result of billions worth of R&D/infra with the intention of producing tens of millions to billions of devices.
