For example, on my desktop (which definitely benefits from the increased compression Zstd can do as I am a VERY heavy user of Zram):
zramctl --output-all
NAME DISKSIZE DATA COMPR ALGORITHM STREAMS ZERO-PAGES TOTAL MEM-LIMIT MEM-USED MIGRATED COMP-RATIO MOUNTPOINT
/dev/zram1 45G 634.5M 344.7M zstd 9859 348.1M 0B 2.6G 193.5K 1.8229
/dev/zram0 15.7G 15G 5.4G zstd 27985 5.5G 0B 5.6G 124.4K 2.7110 [SWAP]
Still the most you see is a compression level of 2.7110, nowhere near the 3.37 tested in your image.
