It seems REPL package in Julia 1.9 introduced new feature

"Add ability to add output prefixes to the REPL output and use that to implement an IPython mode"

Ref: JuliaLang/julia#46781

LineEdit.jl has the following function that adds \e[1m\e[0m (:bold, :normal)

function write_output_prefix(io::IO, p::Prompt, color::Bool)
    prefix = prompt_string(p.output_prefix_prefix)
    suffix = prompt_string(p.output_prefix_suffix)
    print(io, prefix)
    color && write(io, Base.text_colors[:bold])
    width = write_prompt(io, p.output_prefix, color)
    color && write(io, Base.text_colors[:normal])
    print(io, suffix)
    return width
end

and the display method in REPL.jl calls the function above:

function display(d::REPLDisplay, mime::MIME"text/plain", x)
    x = Ref{Any}(x)
    with_repl_linfo(d.repl) do io
        io = IOContext(io, :limit => true, :module => active_module(d)::Module)
        if d.repl isa LineEditREPL
            mistate = d.repl.mistate
            mode = LineEdit.mode(mistate)
            LineEdit.write_output_prefix(io, mode, get(io, :color, false)::Bool) # <-- HERE
        end
        get(io, :color, false)::Bool && write(io, answer_color(d.repl))
        if isdefined(d.repl, :options) && isdefined(d.repl.options, :iocontext)
            # this can override the :limit property set initially
            io = foldl(IOContext, d.repl.options.iocontext, init=io)
        end
        show(io, mime, x[])
        println(io)
    end
    return nothing
end
