It’s a problem with grph-downsample.lua (or maybe GM), I must research

\loadluafile[grph-downsample]

\setupexternalfigures[
  conversion=lowres.jpg,
        resolution=72,
]

\starttext
  \externalfigure[20200910T115319][height=4cm]
  \externalfigure[old-paper-1140627-638x420][height=4cm]
\stoptext
