Andreas,
instead of using the -colormatrix option try instead using
-vf
scale=in_range=full:in_color_matrix=bt709:out_range=tv:out_color_matrix=bt709
assuming your DPX files are utilising full range encoding
also scale has flags which may or may not affect quality in this case.
IIRC getting them to work can be a bit variable, historically
-sws-flags flag1+flag2 ... used to work, but not last time I tested so
-vf scale=........:flags=flag1+flag2..... was what I last used - best
to double check with -loglevel verbose + check output to be sure.

I am thinking of trying accurate_rnd full_chroma_int full_chroma_inp
bitexact
not that I know what's best or relevant, so trial and error really.
