Thanks! Now you've got me looking at the same setup ... Damn HUKD and its helpful community!
I have the ET-3750 which has the same "PrecisionCore Print Head" with same number of nozzles per colour. Both printers are using same type of ink: pigment black and dye colours (102). Because this printers are using pigment black ink the results on any gloss paper will not be very good as it will try to make black using the colour inks. The initial printed photos were not great, colours were different from what was on my calibrated screen. These were printed using the printer colour management. I have made some custom printer profiles (ICC) for different types of photo papers. Using these profiles I had great results for personal use photos.
I think the 27XX (now 28XX) has an even smaller screen than the 48XX. 1.5" vs 2.5".
If this has the same screen size as the one i bought the (ET-2751) then it is TINY. Much smaller then our (then) 10 year old HP AIO it replaced, and when it's showing you which button to press, it's almost impossible to make out the symbol without looking really closely. That said, i have had a lot less problems with it than the temperamental HP, and the ink tank system was great during pandemic/home schooling, when we had to print a lot of stuff out. Still only 25% through the black and maybe 15% through the coloured inks, and we have printed hundreds of pages. I have found photo prints to be acceptable. Not breath-taking, but fine.
