Nothing unfortunate at all about the new monitor not being OLED. For productivity OLED still sucks, and IPS black is perfectly fine. You can get the 45" if you must have OLED. Pixel density in the 40 model is much nicer, matching 4K 32" monitors.
My next monitor will be 5Kx2K in 39-40" size. Unless OLED can improve burn-in to the point you can get a 7 years warranty, not interested.
It makes no sense to limit this monitor to a B2B sales. Offices do not want monitors with speakers because they cause distractions in open spaces. This should be sold to consumers.
