Those rear projectors went with the last century.
Some folks do use digital projectors in their home theaters but they're not TVs. No tuners or audio. And they are dimmer than even cheap TVs which is a handicap in the age of HDR, which requires strong zone backlighting or direct emission. It can be done but it gets expensive (mid-four figures) at a time when 70" LCD TVs start at $ 600 or so.
Front projectors are generally meant for computer presentations in corporate meeting rooms but they're starting to be phased out in favor of large touch capable LCD screens like Microsoft's SURFACE HUB, SAMSUNG'S FLIP, and Google's JAMBOARD.

Those are even more tablet-like than "smart" TVs.
BTW, one thing people forget is that unlike CRTs and Plasma Panels, LCD has polarization layers behind and in front of the LCD layer to prevent glare and make the image brighter. It gets somewhat technical but the bottom line is that LCDs have the equivalent of top quality sunglasses built in so looking at an LCD screen is
nothing like looking into an LED flashlight. (Definitely not recommended.)

Some people might be sensitive to extended viewing of backlit sources but if so they are few and far between and the fault lies within them, not the technology.
Most of the myths about emissive displays come from the early CRTs, which weren't polarized and did produce eye strain. But that ended decades ago. Today's LCD displays are perfectly safe, otherwise people using VR headsets would be going blind all over instead of just getting vestibular headaches.
