Thank you Even. You are totally right as always. The reason is the broken

Denis,
The maximum of nearest downsampling should be <= maximum of full resolution.
Potential explanations:
- your source file has overviews that contain completely different
values than the full resolution image.
- or perhaps your input_raster_to_resize_with_max_val_92.tiff file has a
.aux
$ gdalinfo -stats -json input_raster_to_resize_with_max_val_92.tiff |
jq '.bands[0].metadata[""].STATISTICS_MAXIMUM'
"92"
$ gdal_translate -outsize 1% 1%
input_raster_to_resize_with_max_val_92.tiff output.tif
