I have done this many times in my applications. I understand that you want your table view to look like it is not a table view, but as if it were on an empty piece of paper.
Just a note for you, the reason why you can see the separation with some images and not so much with others is related to its image texture. When you place copies of the image side by side, they do not have a continuous template, forming obvious visual selections.
Solution: Assuming you have a tableview setting in an xib file, display the background of the table itself to clear →, then set the background of the view itself to any image you like. Then you will have a table view, while the transparent view of the background will be transparent, and only the main view behind it will show its image or color. Displaying your image on this canvas will mean a clear single background image.
