Blurry PDF on Manta?

Is it normal for text to be so blurry in a PDF on the Supernote (Manta)? The images on the right are screenshots from the Supernote Manta, while those on the left are from the iPad Pro. I understand that eInk and OLED can’t be compared 1:1, but the PDF on the Manta is even blurrier than on my RM2.
