I think the question you are asking
would be better directed at the potential end user if you are asking for a preference based on some pictures in further development I think it would require an amount of field testing to get real world feedback
As an installer I'm more interested in the technical specification behind the glossy front plate, are your stats going to be wireless with a receiver or a multi zone setup with additional smart thermostatic valve stats
What is the intended or will be the USP of your stat or stats as the market currently has a well established smart thermostat offering which has areas that could be improved on and the basic stats from my experience are mainly bought from what the wholesaler has on the shelf.
With more new boilers adopting operating protocols like Opentherm and EMS that may offer more opportunity to develop new intellegent thermostats
