Strange, for me, tiffinfo from libtiff-4.1.0 shows the predictor tag:

TIFF Directory at offset 0x8 (8)
   Image Width: 32 Image Length: 32
   Resolution: 1, 1 (unitless)
   Bits/Sample: 16
   Sample Format: IEEE floating point
   Compression Scheme: AdobeDeflate
   Photometric Interpretation: RGB color
   Samples/Pixel: 3
   Rows/Strip: 32
   Planar Configuration: single image plane
   Predictor: floating point predictor 3 (0x3)
