Site works in dezoomify but not dezoomify-rs (watermarked)

[NRHGDW]

Have tried adding referer, user-agent headers
Watermarked randomly in dezoomify-rs, but works fine in dezoomify browser extension.
Here is the debug log: log.txt
This is the result (multiple runs of dezoomify-rs)

Dezoomify web has no issue

Thought maybe it was cookie issue but I don't see a way of providing cookie to dezoomify-rs.

Tried dezoomify direct link today, no watermark

I recalled some servers have gotten smart and introduces server-side watermark. Another site I ran into server-side water mark is haltadefinizione.com. No matter the zoom level once I downloaded using dezoomify-rs, the water marks are always there.
Lovasoa, at that time, commented that the program cannot by-pass server-side water mark.

watermarks can be easily removed with Adobe Photoshop
