I've downloaded 2 binaries. One using docker:

docker run -it -v pwd`:/client registry-proxy.engineering.redhat.com/rh-osbs/integration-fuse-camel-k:fuse-8.0-openshift-rhel-8-containers-candidate-27634-20200410074948 cp /opt/clients/camel-k-client-linux.tar.gz /client/`

and second downloading from indy + extract:
http://indy.psi.redhat.com/api/folo/track/build-48926/maven/hosted/build-48926/org/fuse/camel/k/linux-client/1.0.0.fuse-jdk11-800039-redhat-00001/linux-client-1.0.0.fuse-jdk11-800039-redhat-00001.gz

diffing those two results in "Binary files kamel1 and kamel2 differ

md5 checksums are also different:
(indy)
561ab22df9966b8665c802545e4d7a18 kamel

(docker)
1dc4c23da12234ff936132fce7e92e85 kamel

edit:
also registry-proxy.engineering.redhat.com/rh-osbs/integration-tech-preview-camel-k-rhel8-operator:1.0 differs from the one uploaded to indy
