Color styling for >100 COG GeoTIFF with min/max values in OpenLayers

Question

I have this color style (from 0-90 values range) for a COG GeoTIFF file having a values range between 12 (minimum value) and 50 (maximum value):

const autominmaxrange = {
  color: [
    'case',
    ['>', ['band', 2], 0],
    [
      'interpolate',
      ['linear'],
      ['band', 1],
      0, [0, 89, 179, 0.01],
      90, [255, 234, 0, 5.0],
    ],
    [0, 0, 0, 0],
  ],
};

However, I have >100 COG GeoTIFF files with different min/max range values. I would like that the min/max values will be auto-recognized for each COG GeoTIFF in a single color style (eg. the one above with a gray color scale), how can this be achieved?

Many thanks for any pointers,
