There are some other tags allocated in support of these compression formats:
#define TIFFTAG_WEBP_LEVEL 65568
#define TIFFTAG_WEBP_LOSSLESS 65569
#define TIFFTAG_ZSTD_LEVEL 65564
Just a small note: those 3 last ones are pseudo-tags so that calling code can tune compression parameters, but they are not serialized in the file (similarly to deflate compression level)
