OpenEXR needs a dedicated floating-point pipeline that is not implemented yet.
An EXR may carry named auxiliary channels, multipart images or deep samples, beyond a flat RGB image. A rendered JPEG copy is not an equivalent EXR working file. Channel selection, deep compositing and numeric mapping need explicit engine support; no export of every channel or depth sample is implemented.
EXR can contain multiple image representations with different roles. These are not automatically a timed animation. Selecting an image, preserving a collection or creating several outputs needs explicit engine support; neither a first-image choice nor an all-images export is implemented.
If HDR source content is exported through an SDR representation, it needs a display rendering. Values outside the output range require tone mapping, scaling or clipping; brightness relationships can change. Tone mapping, exposure and colour handling depend on the future engine. Renaming or lossless compression cannot preserve out-of-range values.
Typical JPEG files are lossy. The original standard also defines a separate lossless mode; it is not the usual web or camera JPEG. JPEG uses lossy image encoding in this delivery workflow. Re-encoding can change edges, textures and colours; it cannot recover detail already missing from EXR. Quality, chroma handling and file size depend on the future encoder.

OpenEXR
HDR raster data for rendering and compositing, with named channels and lossless or lossy codecs.

Joint Photographic Experts Group
A familiar format for photographs. JPEG keeps files compact by trading a little image detail for broad compatibility.

Renaming or lossless compression cannot preserve out-of-range values.
Source and target sample models can differ in precision, channel layout, colour space and transfer function. Lossless compression only preserves the samples actually encoded; a precision reduction or colour conversion can already change them. The future engine defines numeric mapping, orientation and colour conversion; canonical depth facts are listed below where available.
EXR: Typed header attributes, Chromaticities → JPEG: Exif, ICC. Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.
